This is just a quick reminder, with the beginning of the new year, that the Canada Revenue Agency Books and Retention Policy requires, in most cases, that you keep all records and supporting documents related to determining your tax obligations and credits for a period no less than six years following the end of the last tax year.

This is relevant right now because often online/electronic records provided by banks and other companies have a deadline for retrieval. For example, bank statements can only be retrieved for the past 18 months for many institutions, so if you miss the deadline you may be short if the CRA requests your documentation.
